  9. 4.1 Setting the ID (BB-ID) Identifying a Chassis

4.1 Setting the ID (BB-ID) Identifying a Chassis


4.1 Setting the ID (BB-ID) Identifying a Chassis
This section describes the setting of the ID (referred to below as BB-ID) required for identifying each chassis in the system.
Set BB-IDs sequentially from 00.
See the following and check the mounting locations and BB-ID setting values of chassis.
- For direct connections between chassis: see Figure 2-3 in "2.4.1 Mounting conditions for general racks."

- For connections through crossbar boxes: see Figure 2-7 in "2.4.3 Mounting conditions for expansion racks."
Note - The default BB-ID value is 00. There are cases where each BB-ID is set by the factory at the time of shipping. A BB-ID has been set for any chassis that is shipped mounted in a rack.
Note - When connecting the SPARC M10-4S used as a standalone unit to a building block configuration, execute the restoredefaults command to return to the factory defaults before setting a BB-ID for it.
  1. Set a BB-ID for the SPARC M10-4S.
    Set the BB-ID by operating the BB-ID switch on the operation panel on the front of the chassis. Set SPARC M10-4S BB-IDs sequentially from 00 to 15.
    a. Confirm that the set BB-ID for the SPARC M10-4S mounted at the very bottom of the rack (BB#00) is 00.

     If it is not 00, set it to 00 with a thin, pointed instrument.
    b. Next, set 01 for the BB-ID of the SPARC M10-4S mounted second from the bottom of the rack (BB#01).

    c. Sequentially set BB-IDs for all the SPARC M10-4S units while checking their mounting locations in the rack.

  1. Check the BB-ID settings of the crossbar boxes.
    A BB-ID is set for a crossbar box when shipped from the factory. Here, check the mounting locations of the crossbar boxes, and confirm that BB-IDs 80 to 83 are set sequentially.
    If a setting is different, change the setting by operating the BB-ID switch on the operation panel on the front of the crossbar box.
